Trim all the membranes off the meat, wash it, then pound it evenly with a meat mallet to about half a centimetre thick.
Season both sides with salt and leave for 15-20 minutes.
Set out three plates: flour in one, beaten egg (mixed with a pinch of salt) in another and breadcrumbs in the third.
Coat each piece of meat first in flour, then in egg and finally in breadcrumbs, making sure it's evenly covered everywhere.
Heat enough oil in a large frying pan over medium-high heat to cover the bottom about 1 cm deep.
Fry the breaded cutlets for 2-3 minutes on one side, then 2-3 minutes on the other, until nicely golden but not dry.
Blot off the excess fat with kitchen paper.
Serve with lemon slices and mashed potatoes or parsley potatoes.

Tips
Pound the meat evenly to about half a centimetre thick — a thicker cutlet burns on the coating before the inside is cooked through.
After breading, don't press the crumbs on firmly — tradition says they should sit loosely, so they separate from the meat and "puff up" while frying.
Fry in plenty of hot fat so the cutlet almost floats in it — this helps create the even, airy coating.
Serve with lemon at once, hot — the coating goes soft if it sits.
Frequently asked questions
What's the difference between Wiener schnitzel and a regular breaded cutlet?
Wiener schnitzel is traditionally made from veal, with a thinner, looser coating; the pork-based breaded cutlet uses thicker meat with the crumbs pressed on more firmly.
Can pork loin replace the veal?
Yes, but technically you'd then get a regular breaded cutlet instead of a Wiener schnitzel — it differs in flavour and texture, but can be made the same way.
